[Boundary condition] Levelset-Barrier Method

[LDTalbot]

Description
Improved Levelset with Barrier method; original method via Zhao et al. (2023).

TODO

• 2D benchmark tests for elastic sliding block on plane.
• 3D benchmark tests for elastic sliding block on plane.
• Benchmark tests for elastic rolling/sliding cylinder/sphere on plane.
• 2D benchmark tests for Mohr-Coulomb sand flume.
• 3D benchmark tests for Mohr-Coulomb sand flume.
• Adhesion functionality.
• "Uphill prevention" (potential versus actual tangent resistance).
• Local PIC contact velocity.
• Damping functionality.
• Violation correction.
• Compatible with B-Bar.
• OpenMP.
• MPI.
• Resume functionality.
• Write tests.
• Const particle size for calculating barrier thickness

Other Edits in PR

• const particle size_ to HDF5 for resume
• particle size_ now a scalar
• assign_traction() in particle.tcc now always uses updated_size rather than size_

Related Issues

• Contact functionality (multimaterial)
• Nomenclature for subclasses/derived classes: want e.g. MeshLevelset, ParticleLevelset
